In sewing, piping is a type of trim or embellishment consisting of a strip of folded fabric so as to form a "pipe" inserted into a seam to define the edges or style lines of a garment or other textile object. Usually the fabric strip is cut on the bias. It may be made from either self-fabric (the same fabric as the object to be ornamented) or contrasting fabric, or of leather.
